[62F] Experiencing severe gastroesophageal and gastrointestinal symptoms

What might be happening

Based on the information you've provided, possible diagnoses include:

• Gastroenteritis: This is an inflammation of the lining of the intestines caused by a virus, bacteria or parasites. Viral gastroenteritis is particularly common and is often referred to as stomach flu. Your recent travel could have exposed you to a new pathogen. Symptoms can include diarrhea, vomiting, nausea, and abdominal pain.

  • Treatment typically involves rest, hydration, and over-the-counter remedies. Antibiotics may be needed if the cause is bacterial.

• GERD Flare: Your pre-existing condition of Gastroesophageal Reflux Disease (GERD) could be causing some of your symptoms, especially the heartburn and upper abdominal bloating. Stress, certain foods, or changes in medication can lead to a flare.

  • Treatment typically involves lifestyle modifications and medications to reduce stomach acid.

• Gastritis: This is an inflammation of the stomach lining. It can cause upper abdominal pain, nausea, vomiting, and a feeling of fullness in your upper abdomen after eating.

  • Treatment typically involves medications to reduce stomach acid.

What you can do

While you should definitely seek care from a healthcare professional, here are some things you can do in the meantime:

1. Stay Hydrated: Diarrhea and vomiting can cause you to lose fluids quickly, so it's important to stay hydrated. Try to sip small amounts of water, clear broths, or rehydration drinks (like Gatorade or Pedialyte).

2. Eat a BRAT diet: If your stomach can handle it, try eating Bananas, Rice, Applesauce, and Toast. These foods are bland and can help make your stool firmer.

3. Avoid triggers: If you notice certain foods make your heartburn worse, try to avoid them. Common triggers include spicy foods, caffeine, and alcohol.

4. Over-the-counter remedies: Antacids can help with heartburn and medications like loperamide (Imodium) can help with diarrhea. However, you should check with a healthcare professional before starting any new medication.

What you should look out for

You should seek immediate medical attention if you experience:

• Signs of dehydration like excessive thirst, dry mouth, deep yellow urine, dizziness, or fatigue.
• Severe abdominal pain or bloating.
• Blood in your stool or vomit.
• A fever over 100.4°F.
• Symptoms that last for more than a few days or get worse.
